[Exim] Removed frozen mails manually

I had a lot of frozen virus mails.
To remove them I stopped Exim
and removed the corresponding files manually from the "input" and "msglog"
directorys.

Is that enough?
Will the files in the db directory updated automatic ?
Will Exim anymore send messages with a subject like
    Warning: message 17AC5R-00019W-00 delayed 168 hours
to the users ?
